Tunable optical topological transitions of plasmon polaritons in WTe2 van der Waals films

Light: Science & Applications, 2023
Naturally existing in-plane hyperbolic polaritons and the associated optical topological transitions, which avoid the nano-structuring to achieve hyperbolicity, can outperform their counterparts in artificial metasurfaces.

Light scattering by a medium with a spatially modulated optical conductivity: the case of graphene [PDF]

, 2012
We describe light scattering from a graphene sheet having a modulated optical conductivity. We show that such modulation enables the excitation of surface plasmon-polaritons by an electromagnetic wave impinging at normal incidence.

Coherent surface plasmon amplification through the dissipative instability of 2D direct current

Nanophotonics, 2018
We propose an original concept for on-chip excitation and amplification of surface plasmon polaritons. Our approach, named nanoresotron, utilizes the collective effect of dissipative instability of a 2D direct current flowing in vicinity of a metal ...

Surface plasmon polaritons in strained Weyl semimetals

, 2020
Surface plasmon polaritons in a strained slab of a Weyl semimetal with broken time-reversal symmetry are investigated. It is found that the strain-induced axial gauge field reduces frequencies of these collective modes for intermediate values of the wave

Extremely short-length surface plasmon resonance sensors [PDF]

, 2008
The impact of the system design on the control of coupling between planar waveguide modes and surface plasmon polaritons (SPP) is analyzed. We examine how the efficiency of the coupling can be enhanced by an appropriate dimensioning of a multi-layer ...
